Physics notes for class 9th chapter 1. Feb 10, 2019 · Physics is the study of matter and energy and how they interact in our universe. Feb 15, 2025 · Physics is a fundamental branch of science that deals with the study of ‘nature’ and ‘natural phenomenon’. . It seeks to understand the behavior of physical systems, ranging from subatomic particles to vast cosmic structures. More broadly, it is the study of nature in an attempt to understand how the universe behaves. Physicists work to gain knowledge of the mysteries of the universe—visible matter makes up only about 5 percent of the universe, meaning there is 95 percent to discover. Its scope of study encompasses not only the behavior of objects under the action of forces but also gravitational, electromagnetic, and nuclear force fields. Contemporary research in physics can be broadly divided into nuclear and particle physics; condensed matter physics; atomic, molecular, and optical physics; astrophysics; and applied physics. Physics is the branch of science that studies matter, energy, and the fundamental forces that govern the universe. Its scope ranges from the infinitesimally small objects studied using the principles of quantum mechanics to the entirety of the cosmos, explored using general relativity.
